FRAME MOUNTING FOR WINDOW SASHES AND OTHER CLOSUEES 5 Claims.

My invention consists in new and improved means for mounting windows, storm windows, screens and other closures in their frames and which will also serve as Weatherstripping to seal the window or other closure against the entrance of cold air.

Among the objects of my invention is the provi sion of means whereby the window, screen or other closure may be easily and quickly mounted in and removed from its frame without the use of tools and without danger of breakage.

Another object of my invention is the provision of means for mounting a Window or other closure in its frame in cases where the latter is out of true.

Although my invention is adapted for use in connection with windows which may be raised and lowered in their frames or with closures hinged to their frames, it is particularly advantageous for use with casement windows and other closures which are stationary when mounted in their frames.

In the accompanying drawings, which illustrate a practical embodiment of the principles of my invention,

Fig. 1 is an interior elevation of a casement window to which my invention is applied.

Fig. 2 is a horizontal cross section taken along the line 22 in Fig. 1.

Fig. 3 is an xterior elevation of the window illustrated in Fig. 1.

Fig. 4 is a broken perspective showing the bar which is attached to the stiles and lintel of the frame or other opening, and the flexible weatherstripping mounted thereon and which engages the side edges and the top edge of the sash or other enclosure.

In the drawings, I indicates the sill of the window frame, 2 the vertical stiles of the frame, and 3 the lintel thereof.

The sash comprises the sash frame 4 in which is mounted the glass 5 in the usual manner. The outer edges of the vertical and top bars of the sash may be rounded as shown at 6.

1 indicates metal bars which have outer surfaces which fit against the inner faces of the stiles 2 and the under face of the lintel 3. The bars are attached in place by screws 3 which are driven into the stiles and lintel.

Adjacent its edge which is toward the outside of the window frame the bar is provided with an inwardly extending flange 9 disposed at right angles to the body of the bar, and mounted on the free edge of the flange is a gasket H) of circular cross section having parallel lips ll between which edge of the flange is inserted to mount the gasket on the flange, the flange preferably being inserted inwardly to the axis of the gasket. The gasket is of rubber or similar elastic material.

The bar 7 is provided with a slot [2 parallel with its rear face and extending from end to end of the bar. The slot is enlarged at its bottom as shown at IS. The front Wall i l of the slot stops short of the adjacent edge of the body ofthe bar. [5. indicates a strip of resilient sheet metal bent cross-sectionally to provide a tongue I6. which is inserted in the slot 62. and has an upset edge H which seats in the enlargement I3 of the slot to prevent the tongue Iii being accidentally disengaged from the slot. When th strip I5 is installed the tongue lt is slid lengthwise into its position in the slot.

The'body of. the strip I5 is bent to extend, at a diverging angle to the tongue IS, in the direction of the flange 9, and at its end is curved to form an arcuate trough It in which the rounded edge 6 of the window sash seats when the sash is in place in the window frame.

The window sash is installed in the window frame by moving the sash toward the frame from the inside of the building, the side and top edges of the sash facing the bodies of the strip 15 at the sides and top of the window frame until the rounded edges of the sash frame spring into and are seated in the troughs l 8 and the outer faces of the sash frame members are forced against the gasket ill, the relative positions of the troughs and the gaskets adjacent thereto being such that when the sash frame engages the gaskets the edges of the window sash engage the trough at the sides and top of the window.

The sash is easily removed by seizing the knobs 99 On the window sash and pulling the sash away from the window frame, which movement will disengage the edges of the sash from the troughs and thus release the sash from the Window frame.

At the top of the Window frame the adjacent ends of the bars I mounted on the stiles and the lintel and their metal strips l5 may be mitered to fit together at their ends. The strip [5 may be omitted at the top of the window frame employing the gasket 50 as the sole packing means at the top of the window.

At the bottom of the window a flat plate 2!] may be applied to the outside of the sash to seal the lower edge of the sash, said plate being provided with vertical slots 2! through which screws 22 may be inserted and screwed into holes in the bottom bar of the sash, the bar being adjusted at the proper level and angle to properly engage the window sill.

It is evident that my invention provides means for quickly installing the sash in and removing it from the window frame and for weatherproofing the window. Again owing to the resiliency of the strips IS the sash may be readily installed in and removed from a window frame which is out of true, and when installed in such a frame the window will be effectually weathertight.

I claim:

1. Means for removably mounting a closure, such as a window sash, a screen sash or a door, in its frame, comprising a bar attached to the inner face of the stile or lintel of the frame, said bar being of a length at least equal to that of the edge of the closure to be engaged and said bar being provided with a flange extending into the opening of the frame and overlapping the edge of the closure, a gasket mounted on the free edge of the flange for the full length thereof and protruding laterally therefrom, a plate of flat resilient metal secured along one of its longitudinal edges to the bar and its body extending toward the flange and diverging from the inner face of the bar, and the free longitudinal edge of said plate being bent to form a trough in which the edge of the closure is seated, the resiliency of the plate forcing the face of the closure into sealing contact with the gasket, and the plate being pressed toward the bar to disengage the trough and release the closure.

2. The structure of claim 1 characterized by the plate being secured to the bar by means of an angular flange formed longitudinally of the plate and held in a longitudinal slot cut in the edge of the bar.

3. Means for removably mounting a closure, such as a window sash, a screen sash or a door, in its frame, comprising a bar attached to the inner face of the stile or lintel of the frame and provided with a flange extending for the length of the bar and inwardly of the opening of the frame, a compressible gasket mounted on the free longitudinal edge of the flange and protruding laterally thereof, and a spring metal plate, of a length equal to that of the flange, attached along one of its longitudinal edges to the bar and biased outwardly from the latter at a diverging angle, the free longitudinal edge of the plate being of trough form to clasp the edge of the closure and hold the same in place and pressed against the gasket, the closure being released by pressing the plate toward the bar.

4. The structure of claim 3 characterized by the free longitudinal edge of the plate, when the closure is removed, engaging the gasket to conceal the flange and provide a finish for the frame.

5. Means for removably mounting a closure, such as a window sash or screen sash in its frame, comprising a bar attached to the inner faces of the opposed stiles of the frame, each of said bars being provided with a flange extending for the length of the bar and inwardly of the opening of the frame, a compressible gasket mounted on the free longitudinal edge of each of the flanges and protruding laterally thereof, and a spring metal plate of the same length as the flange and secured along one of its longitudinal edges to each of the bars and said plates being biased outwardly at a diverging angle from the respective bars, each of said plates having trough-shaped free longitudinal edge portions which clasp the adjacent edges of the closure and hold the latter in place with its surface pressed in sealing engagement with the gaskets, the closure being released by pressing the diverging plates toward the bars.
